In the offering, WildHorse sold 27.5 million shares of its stock at $15 per share, raising proceeds of about $391.7 million.

WildHorse will use proceeds, along with borrowings from its revolver, to fund the remaining portion of its acquisition of about 158,000 net acres in Burleson County, Texas, from Clayton Williams Energy Inc. (NYSE: CWEI).

Proceeds from the offering will also be used to repay in full its existing revolving credit facilities and all notes payable to its prior owners. As a result, the company's existing revolver will be terminated.
